Automated risk assessment tool for AIX-based computer systems

Abstract

A system administrator or service provider executes the risk assessment script that automatically performs a series of hardware, software, and firmware tests on the system. Each test provides the administrator/service provider with a determination output that is standardized into risk assessment levels. Depending on the type of test and the risk level assigned to the determination from the test, the administrator/service provider can recommend various courses of action to reduce the risk to the system.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to system services technology. More particularly, the present invention relates to providing an accurate risk assessment of a computer system. Still more particularly, the present invention relates to a system and method for automatically assessing a system's health and making appropriate recommendations.[0003]2. Description of Related Art[0004]The UNIX operating system, or “UNIX,”“A weak pun on Multics,” is an interactive time-sharing operating system invented in 1969 by Ken Thompson after he left Bell Labs and the Multics project, apparently to play games on his scavenged PDP-7 computer (minicomputer sold by Digital Electric Corp. (DEC), (Compaq Computer Corp., 20555 SH 249, Houston, Tex. 77070)). Thompson developed a new programming language ‘B’, and Dennis Ritchie enhanced ‘B’ to ‘C’ and helped develop ‘UNIX’.[0005]The UNIX operating system is a multi-user operating system supporting serial or...

Benefits of technology

[0034]The present invention relates to a system and method for implementing an automated risk assessment tool which outputs a series of sub-system risk levels that can be used by a system administrator for formulating standardized recommendations. A system administrator or service provider executes the risk assessment script that automatically performs a series of hardware,

Problems solved by technology

When the system becomes overloaded (i.e., where there are more people than the system can handle), the operating system spends most of its time shuttling programs between main memory and the disk unit, and response time degrades.

If the request is invalid or not authenticated, then the operating system does not perform the request but simply returns an error code to the program.

Faults are inevitable in digital computer systems due to such things as the complexity of the circuits and the associated electromechanical devices.

Even with the recent developments in fault-tolerant systems, there are characteristics of UNIX systems that make them difficult to adapt to conventional fault-tolerant operation.

The complexity of UNIX based systems requires that such fault-tolerant systems maintenance and diagnostic systems (or “state machines”) have capabilities that require state-of-the-art systems maintenance and diagnostics systems.

Catastrophic failure is defined as any hardware problem, including but not limited to disk, planar, or adapter anomalies, which c
